Hi I’m Mike Langley and today I’m going to show you how to install one of our new products, the washdown shaft collars. For installation today we’ll need a torque wrench, a rag, washdown collar assembly which consists of a male shroud, metallic shaft collar and female shroud, our o-ting pack and prepackaged lubricant. Use the collar assembly as received, do not clean, lubricate or otherwise alter except as instructed. If there is any incidental dust or debris, it should be removed before assembling. For warranty information, please visit www.Ruland.com/warranty. We are now ready to begin the installation.

Disassemble the plastic shroud by unscrewing the two halves, remove the metallic shaft collar and discard shipping material. Remove the o-ring from their packaging and lightly coat using prepackaged lubricant leaving an even film but leave excess lubricant for use in the assembly process. Seat the two smaller o-rings in the internal bore grooves found on each half of the plastic shrouds. Then install the remaining o-ring into the external grooves on the shroud half with the male threads. Next wipe the bore of the metallic shaft collars clean and apply a thin film of excess lubricant. For proper performance, the shroud half with the external threads and o-ring should be positioned nearest to the applied load. You must assess which orientation is correct for your application. In our setup install it this way. Assemble the collar into the mail half of the shroud by making sure the grooved face is pointed inwards and then align the two positioning pins on the shroud with the corresponding holes on the face of the collar. If installed properly, the screw access notch will line up with the screw and the shroud will run with a consistent amount of metallic on expose on both sides. If your collar looks like this, the pins may not have been seated fully or there may be contaminants between the collar face and the shroud. Repeat the pin insertion steps, making sure the face groove is pointed inward and the collar is free of contaminants. Next slide the partial assembly onto the shaft into the desired position. If the assembly is against the bearing face, apply any necessary pre-loading. Tighten the socket screw to the recommended seating torque with an appropriate torque wrench. This is an M4 screw with a seating torque of 4.6 newton meters. All seating torque information can be found on Ruland.com. Slide the female half of the shroud onto the shaft towards the assembly and twist the two halves together to seal. If the male shroud is held in place against the face, grip the shaft with a fist behind the male shroud pressing against the collar. Then twist the female shroud into place. Hand tighten only as this will create a strong enough seal to make the disassembly significantly easier. Last wipe off any excess lubricant that remain on the shaft or collar surface. Your shaft collar assembly is now complete. Thank you for viewing this video. For more installation videos as well as technical information and CAD models, please visit Ruland.com.

Installation Instructions

  1. Use the collar assembly as it is – do not clean, lubricate, or otherwise alter except as instructed in this document, but remove incidental dust or debris before assembling.
  2. Disassemble the plastic shroud by unscrewing the two halves, remove the internal metallic collar, and discard the foam shipping material.
  3. Remove the three O-rings from their package and lubricate with the provided lubricant. Wipe off any excess lubricant, being sure to leave an even film. Save the excess lubricant for use in the assembly process.
  4. Seat the two smaller O-rings into the internal bore grooves found on each half of the plastic shroud.
  5. Install the remaining large O-ring into the external groove on the shroud half with the male threads.
  6. Wipe the bore of the metallic collar clean and apply a thin film of the lubricant provided with the O-rings.
  7. Determine the proper orientation for the assembly based on the application. The shroud half with the external threads and O-ring should be positioned nearest to the applied load for proper performance.
  8. Assemble the metallic collar into the male half of the shroud by making sure that the face groove on the collar faces towards the shroud and then aligning the two positioning pins on the shroud with the corresponding holes on the face of the collar. If installed properly, the screw access notch should line up with the socket screw and the shroud should run true with a consistent amount of the metallic collar exposed on all sides. If not, ensure the pins are seated fully, and there are no contaminants between the collar face and the shroud.
  9. Slide the partial assembly onto the shaft and into the desired position. If the assembly is against a bearing face, apply any preload that is necessary.
  10. Tighten the socket screw to the recommended seating torque using a hex wrench.
  11. Slide the female half of the shroud onto the shaft towards the assembly and thread the two halves together to seal. If the male shroud is not held in place against a surface, assembly is most easily accomplished by gripping the shaft with a fist behind the male shroud and pressing against the collar with one hand and twisting the female shroud on with the other. HAND TIGHTEN ONLY.
  12. Wipe off any excess lubricant that remains on the shaft or surface of the assembly.
